Term | Definition |
---|---|
aggregate supply | quantity of goods and services that producers are willing and able to supply at a given level of prices in each period |
SRAS | short run aggregate supply |
short run aggregate supply | relationship between planned national output and general price level |
GDP | planned national output |
GPL | general price level |
rise in general price level does what to SRAS | expansion of SRAS as businesses respond to the profit motive |
fall in general price level does what to SRAS | contraction of SRAS as production contracts |
which way does SRAS slope? | SRAS is upwards sloping as there is a positive relationship between the price level and real GDP |
what happens when the economy has plenty of spare capacity? | SRAS is elastic and the output gap is negative |
causes of shifts in SRAS | resource prices(wage costs per unit of output, labour productivity, raw material, energy costs)/business tax, subsidies, regulations & imported costs(VAT, size & scale of fiscal, enviro or employment tax)/cost of imported components/supply shocks |
external factors affecting aggregate supply | world oil(UK is net importer of oil) and gas prices/other mineral and metal prices/foodstuff prices/import tariffs(increase prices of imported) or quotas(limit quantity of imports so scarcity causes price rises) |
sticky wages | when workers' earnings don't adjust quickly to changes in labor market conditions |
Phillips curve | inflation and unemployment have an inverse relationship |
Keynesian aggregate supply curve | non-linear where the elasticity of aggregate supply is dependent in part on the amount of spare productive capacity at different stages of the economic cycle |
full employment | a situation in which all available labour resources in an economy are being used, and there is no significant surplus of unemployed workers |
neoclassical economists move the SRAS if | costs of production change |
neoclassical economists move the LRAS if | the quantit and/or quality of factors of production change |
